Belated entry, happened last year when everyone else was off and I was covering the whole SouthBay by my onesies. Had a trouble report for the Lomita central office -- one of the telephones alongside the frame was broke. Yeah, we installed a wireless system -- but the handsets have to be programmed to each office, any roving frame attendents still need to use the old KTS system. Which means we still have to maintain it. When we retire they will be forced to kill off the KTS as no one will know how to fix it.
